The ceramic will help but only just a little . I've made some shields in the past using 1/4" solid stock welded to the pipe about 1/4" long in a straight inline pattern along the pipe , two rows of them and then using a pipe about 33% larger spot welding that to the standoffs which could be done after coating .
I had a very heavy skidplate on my last rig - got hit in the rear by a gal in a Ford one day and thankfully that skid kept the tank from being punctured although it did get dented in quite a bit . That 2" receiver acted like a drift punch and even tore the 3/16" skid plate . Totaled the car , cost me half a day and some steel to fix the rear bumper/skid .... lol .
